Vitamin D deficiency diseases

Vitamin D is known as the sunshine vitamin because the body naturally produces it when the skin is directly exposed to sunlight. According to scientists, about 75% people have inadequate levels of vitamin D and symptoms of vitamin D deficiency. Unfortunately vitamin D deficiency was linked with increased risks for serious diseases including cancer, cardiovascular disease, osteoarthritis, autoimmune disorders, multiple sclerosis, type 1 diabetes, depression and some other health conditions.

Vitamin D deficiency diseases – cancer

According to scientists, vitamin D plays vital role in cancer development, especially breast cancer development. Women with breast cancer tend to have low levels of vitamin D and women with higher levels of vitamin D are less likely to develop breast cancer. At the same time, it was noted that breast cancer suffering women with higher levels of vitamin D have higher chances for survival – they usually have smaller tumors and are less likely to die from breast cancer.

Concerning prostate cancer, it was found a link between low blood levels of vitamin D and aggressive prostate cancer. The connection between vitamin D and prostate cancer was especially strong in African-American men.
Scientists are trying to prove the connection between vitamin D deficiency and other types of cancer.

Vitamin D deficiency diseases – cardiovascular disease

Vitamin D deficiency diseases

Several factors are responsible for cardio-vascular diseases including vitamin D deficiency which was associated with an increased prevalence of hypertension, hyperlipidemia, peripheral vascular disease, coronary artery disease, myocardial infarction, heart failure and stroke. According to health experts, the anti-inflammatory effect of vitamin D could play the main role. Low levels of vitamin D have been linked to more severe cases of heart disease and increased mortality (death) from cardiovascular disease was noted in clients with decreased levels of vitamin D.

Vitamin D deficiency diseases – infections

Some studies confirmed the association between decreased levels of vitamin D and increased risks of both upper and lower respiratory tract infections. Studies show decreased level of vitamin D in patients with tuberculosis. Scientists explain it by vitamin D anti-inflammatory and anti-infection ability.

Vitamin D deficiency diseases – multiple sclerosis

Scientists suggested also links between vitamin D level and multiple sclerosis. The mechanism of this phenomenon is not clear yet.

Vitamin D deficiency diseases – dementia

Scientific study published in Journal Neurology (2014) found that moderate-to-severe vitamin D deficiency in older people could double the risk for some forms of dementia, including Alzheimer’s disease. Dementia is a decline in thinking, behavior, and memory that negatively affects daily life. According to this study, adults with low levels of vitamin D had 53% increased risk of developing dementia.

Health experts suggest that the sunshine vitamin might help clear plaques in the brain linked to dementia.

Vitamin D deficiency diseases – schizophrenia

Several studies confirm that vitamin D deficient are twice as likely to be diagnosed with schizophrenia as compared to people with sufficient vitamin D levels.

Vitamin D deficiency diseases – diabetes type 2

People with blood vitamin D levels over 25 ng/mL had a 43% reduced risk of developing type 2 diabetes compared with those with levels under 14 ng/mL. Future studies are needed.

Vitamin D deficiency diseases – erectile dysfunction

According to study published in the Journal of Sexual Medicine (2014), men with severe erectile dysfunction had significantly decreased levels of vitamin D comparing with men with mild erectile dysfunction.

Vitamin D deficiency diseases – sleep apnea

There is some scientific evidence that vitamin D deficiency could increase risks of obstructive sleep apnea brought on by inflammatory rhinitis and tonsillar hypertrophy.
